ZigBee无线网络对各子区域进行分布式控制。每个子区域作为一个ZigBee节点由一片CC2530控制实现显示、通信、检测等功能。所有节点硬件设计相同，均含高频核心板与低频底板。主控制模块与远程控制中心通信，生成各子区域的点阵显示数据并传送给协调器。使用Z-Stack协议栈在基于事件处理的多任务构架下设计了用户程序，实现了单播和广播通信，以及基于有限状态机的串口通信。高频核心板＋低频底板的结构可降低PCB制板成本并提高电路板通用性和互换性。该设计增加了系统稳定性和可靠性，防止了故障扩散，减少了维修频度，还能将数据吞吐量分担到多个 CPU 上，使整个系统成为多核并行处理机。","authors":[{"authorName":"张飙","id":"f7b1485f-1598-4064-9c33-9afcd1c5a8ac","originalAuthorName":"张飙"},{"authorName":"周国清","id":"179e320f-9e72-4842-919b-218fb08e6933","originalAuthorName":"周国清"},{"authorName":"杨小平","id":"ef0cdc7a-8905-49e8-9a3b-b0219fb95aa2","originalAuthorName":"杨小平"},{"authorName":"<span
